[Pcsclite-muscle] PCSC proxy mode and READER_STATE struct

[Andrey Af]

Hi Ludovic,
I found my mistake, I confused SCARD_STATE from PCSC and SCARD_STATE
from Microsoft.

Ok. let's say I implemented an interface for the RDP protocol.
https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-rdpesc/60d5977d-0017-4c90-ab0c-f34bf44a74a5

So, I have all these calls - EstablishContext, ListReaders,
GetStatusChange ant etc.
I want to deliver remote smartcards to a local system. How do I
interact with the PCSC-LITE API?
Please tell me the right way.
